I am sure you will not be able to find a decent leech anywhere around there. I would take up some nice fat crawlers, and spend a few bucks and get some redtails, if they are available. I don't know what the water temperature is, but I will assume most decent walleyes are either in the deep water or in the shallows. If you are a night fisherman, I would definitely try the shallows, meaning as little as 3 to 5 feet. During the day, head for deep holes around mid lake "humps"-35 to 40 feet should be a good depth to start. As always, hug the bottom.
